How Installing Energy-Efficient Windows in Wolcott Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
- Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Wolcott
Each window replacement company provides varying services and has varying costs depending on a few factors.
How Much Do New Windows Cost?
Typically, Wolcott homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will add extra costs to your project.
It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Wolcott homeowners $420+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the complete window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re still trying to decide which type of installation to get, you can consult with your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Wolcott
In our hunt to make your home improvements easier and more eco-friendly in Wolcott, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, cost, warranty, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Wolcott’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Wolcott window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

The most common kinds of windows for homes include: casement windows, slider windows, awning windows, bay windows, double-hung and single-hung windows, transom windows and picture windows.
Can you install your own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
How often do you need to replace windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
